2V0-41.24 Question 116
Select 3An organization is deploying a multi-tier application using NSX-T Data Center. The application requires external connectivity and has distinct requirements for separating web, application, and database tiers. The network administrator configures a Tier-0 Gateway for external connectivity and multiple Tier-1 Gateways for internal segmentation. What must the network administrator ensure to establish proper connectivity between the application tiers and the external network?
- A
The Tier-0 Gateway and Tier-1 Gateways must be linked.
- B
Route advertisement must be enabled on the Tier-1 Gateways for the required networks.
- C
Tier-1 Gateways must have NAT rules configured to allow external traffic.
- D
The Tier-0 Gateway must be configured with an external interface for north-south traffic.
- E
Both the Tier-0 and Tier-1 Gateways must be configured in Active-Active mode.
Show answer and explanation
Correct answers: A, B, D
Explanation
To ensure proper connectivity between the internal application tiers and external networks, the Tier-0 and Tier-1 Gateways must be linked, and route advertisement must be enabled on the Tier-1 Gateways to propagate internal network routes to the Tier-0 Gateway. Additionally, the Tier-0 Gateway requires an external interface to handle north-south traffic. NAT rules and Active-Active mode are not mandatory unless specific design requirements dictate their use.
- A. Correct.
Correct. Tier-0 and Tier-1 Gateways must be linked to provide connectivity between the internal and external networks.
- B. Correct.
Correct. Route advertisement on Tier-1 Gateways ensures that the required networks are advertised to the Tier-0 Gateway for external connectivity.
- C. Incorrect.
Incorrect. NAT rules are not mandatory unless specific NAT requirements exist. For general connectivity, routing is sufficient.
- D. Correct.
Correct. The Tier-0 Gateway must have an external interface to handle north-south traffic, which connects the application to external networks.
- E. Incorrect.
Incorrect. Active-Active mode is not a requirement for connectivity; Active-Standby mode can also be used based on the organization's design.
